Toptutors - AI-Powered Tutoring Platform

building features, fixing infrastructure, and shipping AI-powered learning tools.

The Challenge

Toptutors is a Danish tutoring marketplace expanding into AI tutors and learning tools. When I joined, they had an early AI chat live but a lot of foundational issues - buggy cron jobs, unreliable notification systems, and infrastructure that needed hardening as the platform scaled.

What I Did

Built the documents system using Tiptap with AI chat integration
Implemented slash commands and toolbar AI commands (Notion-style UX)
Created learning journeys feature
Improved the chat system and added AI capabilities
Architected event-driven backend supporting 10k concurrent connections
Reduced backend latency 20% through PostgreSQL optimization and Redis caching
Set up observability on endpoints I implemented using Sentry, catching 35% of issues before users saw them
Fixed Stripe payment flows, reducing payment-related bugs by 23%
Built internal CLI tools that cut debugging time from hours to minutes
Fixed bugs daily, shipped PRs constantly
